Prince Harry and Meghan Markle posted a new photo of royal baby Master Archie on Instagram to celebrate Meghan’s first US Mother’s Day.

The image captured Meghan holding her son’s tiny feet in the palm of her hand. The picture was shared on the couple’s official Instagram account on Sunday.

Alongside the adorable picture of baby Archie’s tiny toes was a hidden message in the background.

Meghan held baby Archie in front of purple forget-me-nots flowers, which were in fact Princess Diana’s favourite, to pay tribute to Prince Harry’s late mother who passed away when he was 12 -years-old.

Prince Harry also chose these special flowers for Meghan’s bridal bouquet in memory of his mother.
